Even though the phrase ‘There’s no such thing as a free lunch’ remains a truism, however cynical, it doesn’t seem to stop Scosche from using the promise of ‘something for nothing’ to tempt you to buy its Solbat2 solar-powered backup battery.

Sooooo....

t'other halfs phone

This would be ideal -assuming we had decent weather- for my other halfs phone. It usually goes about a week between needing a charge so if we left it in the bedroom window for a week, then charged the phone every now and again it would be cool.

Even..

..if it charged in six hours, the idea that a lump of plastic with a solar cell and a lithium ion battery shipped for the far east is going to be less environmentally damaging or more economic than taking 5Wh from the grid/car/plane is just stupid.

As a reserve battery I guess it works ok, I bet however if someone did the maths the 1KWh or so of energy this thing is going to provide in its lifetime, won't offset the carbon used to manufacture, integrate and ship that solar panel.

Five days????

I'm appalled. Why even sell such a thing?

I'm planning a two-week cycling trip which will mostly involve camping, and was looking for a way of charging on-the-go, specifically for charging music player/phone for tweeting etc. Looks like I won't be going the solar option...

"I'm planning a two-week cycling trip .."

Fit your bike with a dynamo and recharge your batteries from that. If you want, you can reach down and disengage it before you go uphill, or only engage it on the downhill stretches; but watch your fingers! (Do they still make them? I remember them from 'the old days' when I had a bike.)

You could....

overcome the time and weather by buying 5x for 5 sunny says plus a few more depending how non-sunny you expected it would be. So a string of about 25 of them dangling from your sporran would sort you for a week of Munro bagging.

Not clear...

Is this 5 days based on UK weather, or that of a warm & sunny country? I can see a few uses for it in the latter, in bars with a "we don't let you plug in your charger for insurance reasons," for example, or simply on the beach.
